You are correct, however we replace just as many belt driven pumps as chain driven pumps, possibly more.So, the RWD vehicles using this engine don‘t have this same water pump issue? It’s just the FWD/AWD versions because the pump was packaged inside in order to fit the engine in transversely? So a RWD F150 or RWD Transit don’t have this problem... because the water pump placement is mounted differently/normally?
PG coolant never took off - it’s more expensive than plain-Jane green(but new xOAT coolants are too) and the OEMs never wanted to use it. It’s safer to pets and wildlife but needs different refractometers and doesn’t behave like EG does.Originally Posted by IMSA_Racing_Fan
Was going to post a thread on this but will just mention it here:. what is the deal with that pink alcohol based RV/power equipment coolant that is strictly prohibited for cars/trucks? Is it simply a fire hazard issue?
RV antifreeze is propylene glycol based, not "alcohol" (yes it has hydroxyl groups). And it has no corrosion inhibitors or at least ones unsuitable for automotive use.

I smell major b.s. with this comment
Really, no level sensor? Even old saturns sl1s have a coolant level sensor.I looked at a lincon MK? with that high mileage, had that engine (or the 3.7). Dealer said it isn't that common but if it happens it happens. According to him and his techs nothing can prevent it. He had the old part from one he just repaired, and it had lots of play in the shaft.
If any coolant came in contact with the bearings that get play that would be a problem in itself.
He said MAYBE a coolant level sensor in the bottle (ironic it don't have one, some cars have sensors for the washer fluid!) but he said said it usually happens catastrophically on the highway and there is nothing you can do. Maybe install a float switch.
If you are that worried maybe PM the part.

So is a chain considered a scheduled replacement part? I've never replaced the chain in my old ECHO, and the water pump I changed at about 280K miles just because I thought nearly 20 years was long enough.
Conventional oil every 3k miles on my families 2010 Taurus right about 240k miles when the water pump failed. Sold to a mechanic who fixed it, chains were stretched to the max. Maybe thinner oil doesn't protect as well but it has nothing to do with being synthetic. I wonder if the chains would have lasted longer with synthetic.Its not a coolant issue. Its a thin oil issue.
